Abstract
Disclosed is a method and apparatus for controlling the operation of a Cochlear implant prosthesis to optimize the effect of stimulation for a given patient. The optimal operation mode is determined in accordance with predetermined parameters measured from the neural response of the patient's auditory system in response to a neural stimulation.
Claims55
A method for optimizing a speech processing strategy configured to convert a speech signal into an electrical stimulation signal in a cochlear implant having one or more electrodes implanted in an inner ear of a patient, the method comprising:
- measuring with said one or more electrodes at least one spatial property of a neural response of the inner-ear of the patient;
- and
- adjusting a strategy parameter of said speech processing strategy based on said at least one neural response property.
A method for optimizing a conditioning stimulus delivered via one or more electrodes implanted in an inner ear of the patient, the method comprising:
- measuring with said one or more electrodes at least one property of a neural response of the inner-ear of the patient;
- and
- adjusting said conditioning stimulus so as to maximize stochastic variability provided by said conditioning stimulus based on said at least one neural response property.
A method for selecting one of a plurality of speech processing strategies each of which converts speech signals into electrical stimulation signals in a cochlear implant having one or more electrodes implanted in an inner ear of a patient, the method comprising:
- measuring with said one or more electrodes at least one property of a neural response of the inner-ear of the patient;
- and
- selecting one of said plurality of speech processing strategies based on said at least one neural response property,
- wherein said at least one neural response property is a spatial property of said neural response.
A method for selecting one of a plurality of speech processing strategies each of which converts speech signals into electrical stimulation signals in a cochlear implant having one or more electrodes implanted in an inner ear of a patient, the method comprising:
- measuring with said one or more electrodes at least one property of a neural response of the inner-ear of the patient;
- and
- selecting one of said plurality of speech processing strategies based on said at least one neural response property,
- wherein said at least one neural response property is a spatio-temporal property of said neural response.
